Abstract:
Le connecteur de sécurité (1) à aiguille comporte un manchon protecteur (4) tubulaire à tronçon distal dans la paroi périphérique duquel est ménagée une portion de paroi déplaçable (100). La portion de paroi déplaçable (100) est sélectivement déplaçable entre une position de retrait et une position de protection. En position de retrait, la portion de paroi déplaçable (100) est alignée avec la paroi périphérique du tronçon proximal de manchon protecteur (4) tubulaire. En position de protection, la portion de paroi déplaçable (100) fait saillie dans l'espace intérieur (7) du manchon protecteur (4) tubulaire.
Abstract:
An I.V. infusion or blood collection apparatus comprises an I.V. infusion set (100) and a safety shield (200). The I.V. infusion set has a wing body (105) from which a pair of wings (140) extend outward there from and a grip (145) extending upward there from. One end of the wing body mounts a needle (120) or catheter and medical tubing (130) is connected to the opposite end. The wing body includes a bore so that fluid flows between the needle and the medical tubing. A safety shield has a top, a bottom and opposing side walls and defines a cavity (227) that is adapted to receive the I.V. infusion set. The safety shield has slots (250) in each of the side walls and a slot (255) in the top. The respective wings and grip are adapted to be positioned in the slots and to slidably move therein. The slot in the top includes a lock that is adapted to receive the grip so that when the needle is retracted into the cavity; the grip is permanently captured therein, thus locking the needle in the fully retracted safety position.
Abstract:
A lancing device (1) for use with a lancet (7) for obtaining a blood sample is disclosed. The lancing device comprises a housing (2); a probe (10) disposed in the housing (2); and a probe actuator (15) for linearly displacing the probe (10). The probe (10) is configured for releasably engaging a lancet (7) and is provided with sliding surfaces for slidably (32, 33) engaging a pair of guides (23, 24). Each sliding surface (32, 33) has a radius of curvature centred about a curvature defining axis, the curvature defining axis being coincident with a central longitudinal axis of the lancet (7) when the lancet is engaged by the probe (10). The sliding surfaces (32, 33) are continually biased against the pair of guides (23, 24) such that when the lancet (7) is engaged by the probe (10), the lancet (7) is prevented from translating in any other direction than in a direction parallel to its central longitudinal axis during linear displacement of the probe (10).
Abstract:
A blood collection assembly includes a housing and a cannula extending distally from the housing including a patient end, and a cannula shield removably engaged with a portion of the housing. The cannula shield is capable of shielding at least the patient end of the cannula, and includes a safety shield engagement. The assembly includes a pivoting safety shield engaged with a portion of the housing, which is transitionable from a retracted position in which the patient end of the cannula is exposed, to an extended position in which the patient end of the cannula is shielded by at least a portion of the safety shield. The safety shield includes at least one locking tab releasably engageable with the safety shield engagement, wherein the locking tab is fixedly engageable with a portion of the housing in the extended position.
Abstract:
Systems and methods are disclosed for identifying and deploying a protective cover about a percutaneous puncture site formed by a hypodermic needle. In the preferred embodiment, a marking agent or puncture site covering, the latter of which preferably takes the form of a bandage, is releasably secured upon either the needle hub of the hypodermic needle or on a sliding member or sleeve axially moveable along the length of said needle that forms a marking or detaches therefrom once compressed about the puncture site.
Abstract:
Point protection and method for use at hypodermic puncture needles characterised by that the point protector's active protection function is effected by a thin walled tube that externally or internally is closely fitted to the puncture needle (1) so that a supporting, evenly distributed normal pressure on the thin walled tube arises which substantially increases its capacity to sustain the forces that after accomplished tissue penetration may be expected to affect the protector, without embarrassing deformation, and by that prevent accidental scratch, chafe and/or stab injuries caused by the sharp needle point inclusive tissue damages at punctured tissue for instance at the inside punctured blood vessels, the so-called endothelium.
Abstract:
A needle guard (62) attached to the barrel (64) of a hypodermic syringe encloses and shields the needle (112) against contamination prior to use and prevents inadvertent direct contact therewith by medical personnel after use. Development of an aperture (104) at the end of the needle shield (62) to accommodate protrusion by the needle (112) is effected by a removable member (98). Translation of the needle guard (62) along the syringe barrel (64) to uncover and recover the needle (112) is effected by manipulation from a location rearwardly of the needle point to further protect the medical personnel. A single ended needle (180), detachably attachable to a hypodermic syringe (182), includes a posteriorly and anteriorly translatable needle guard (184) to uncover and recover, respectively, the needle (206). A double ended needle (64), usually used with a collection tube holder (66) of the blood evacuation system, includes a needle guard (62) which may interlock with the holder (66) upon translation of the needle guard (62) to expose the anterior needle (112).
